Hi CQ,
A sophomore is a 10th grader and they are about 16 yrs. old depending on when they started school some
students start at age 4 others at age 5 it all depends on if their birthday is by a certain date in January.
Here is the U.S. we start school in September and are finished in June. Elementary school is from ages 4- 10
then there's Jr. High school which is 6th-8th grade and the students are 11-14 and then off to High school and most
students graduate by the age of 17 or 18 yrs. old.
When I was in school the elementary school was K- 6 then high school was 7th grade through 12th grade but the
school I worked at has so many students that they had to split them up.
Here's wishing You Well and May God Bless You,
Sue
Thanks Sue
In a way the age groups are pretty much the same

, it’s just we just call it primary school and high school. I’ve knew you guys were different but I always forget how it works with the ages.
We’re the same it depends on when the child’s birthdate is as to when they start school. I think if they were born in the middle of the year they could start at 4 and turn 5 while in their 1st year of school.
Im not sure when it is now but back when I went school you had to be 5 after June to start school. I was born in September so I was already 5, my siblings were all born earlier in the year with 2 of them having birthdays at beginning of June so they were 4
When you start school it is either kindergarten or prep, it’s crazy it depends on the state you live in. Where I went to primary school it was kindergarten. When I finished primary school we moved to another town in the next state but just on the other side of the border and they call it prep

.
I know you guys are on Summer vacation at the moment so schools on their big break if I’m right?
I’m not sure how long you have off but our summer school holidays is 6 weeks. Last day is end of December and they usually start back end of January as we have Australia Day on 26th January.
